Product Description
Submersible centrifugal aerator
Function
Used in aeration basin,aeration grit basin of sewage treatment plants, to fill oxygen and mixing to sewage –sludge mixing liquid, biochemical treatment to sewage and breed aquatics increase oxygen.
Feature
1) compact structure,small occupy area,install convenient
2 ) except air inhale inlet , other parts all diving into water operation,small noise;
3) inhale much air,produce more thin air bubble , with high dissolved air rate;
4) No need supply air source, save air blower, little project investment
5)Adopting Germany ABS submersible sewage pump technique, impeller passage adopt no-jam, safe operation and reliable
Principle
QXB submersible centrifugal aeration adopt motor and impeller driven directly, drainage around water forming low pressure area to inhale water flow by using impeller rotary generate centrifugal force , make vacuum in impeller entrance and inhale air, air and water fully mixed to form unique air water mixing liquid in mixing air chamber, and discharge out quickly in the action of centrifugal force.
Due to water flow jet is strong, cause effective water flow circulate, to make the air shear into vast tiny air bubble, greatly increase its surface area, and due to air bubble ascend slowly to make large oxygen dissolved into water, which to make this aerator effective superior than other aerator.
technical requirements
1. The submersible centrifugal aerator consists of submersible motor, air inlet pipe, mixing chamber and aeration plate, etc.
2. Submersible centrifugal aerator can within the prescribed scope of work, there is no cavitation occurs, run less than 70 db noise, smooth operation, the motor has the enough power rating.
3. Submersible centrifugal aerator of all pressure parts for pressure test, the test pressure for the 2 times the design pressure, but not less than 0.2 Mpa, lasts for 5 min and no leak phenomenon.
4. Submersible centrifugal spray aerator epoxy anticorrosive paint, coating thickness is more than 300 microns, the surface light, no sand holes, cracks, etc., flow components with spray epoxy anticorrosive paint.
5. The submersible centrifugal wheel aerator, rotor dynamic balance test, balance to G6.3 precision.
6. Each submersible centrifugal aerator lifting ear in the cover near the center of gravity of the aerator, solid and reliable.
Main Material
1.Submersible centrifugal aerator frame, chassis, such as using HT250 cast iron casting, has certain corrosion resistance, and can withstand a certain load impact.
2. The submersible centrifugal aerator motor shaft manufactured 2 cr13, Taken in the structural design of the measures to eliminate the stress concentration.
3. Bearing of submersible centrifugal aerator adopts NSK bearings, its cumulative operating life of design ensures that in more than 40000 hours.
4. The submersible centrifugal aerator static seal of the nitrile butadiene - 70 type O ring.
structural features
1.Submersible centrifugal oil cavity chamber and motor aerator with leakage protection alarm function, adding more than 5.5 kW motor winding overtemperature alarm switch.
2. Submersible centrifugal aerator adopts high efficiency non-clog impeller design, as the channel impeller, the impeller for whole casting, between the impeller and shaft adopts the internal locking locking devices, the impeller can be easily drawn from the bottom.
3. Cable wire sealing adopts special rubber sealing head, can easily be replaced and can effectively seal, cable USES YCW type oil rubber sets of cables, cable length randomly to 10 m, or according to the demand of users.
4. Submersible centrifugal aerator adopts mechanical seal structure for sealing, respectively in the oil chamber, ensure proper and reliable work, oil chamber has enough space to accommodate the expansion of the oil, and can be easily replaced.
5. Motor USES the diving squirrel-cage induction motor, protection grade IP68, with class F insulation of stator winding, stator winding with class H insulation, maximum starting current is not more than 5 times the rated current, efficiency is 85 ~ 95%, full load power factor is 0.8 or higher.
